As a reader this makes me think the post means the following
5th > 8th > 4th, as the ability to host a 1st round game would be amazing!
The the original poster did not clarify. But I am guessing this was his overall message. So stop insinuating that they said 8th > 5th seed. . . Because they never said anything of the sort.
The only reason #8 is better, you get to host the #9 team in the country, then you get to play the #1 team in the nation! That is definitely a cooler lineup (even if more difficult) than hosting #12 before playing the #4 team. Some people enjoy playing the best of the best!
With that in mind, I still think #5 > #8 seed.
